Active Band Switching Solutions Written By: Alessandro Beretta Abstract: Today’s new and emerging wireless applications are increasingly requiring the support of multiple frequency bands. From laptops to cellular phones to wearables, devices are expected to connect to any cellular, Bluetooth™, GSM, RFID, or other networks. These expectations present challenges when it comes to antenna design, compared to a traditional design. The simplest solution — using discrete antennas for each frequency band required in the application — requires extra physical space. But this ultimately clashes with industry trends that prefer smaller and smaller solutions while still providing more bandwidth.
Connectivity is key in today’s world and devices in the market require strong signal strength to allow for peak performance. Integrating an antenna is not trivial, whether it is an off-the-shelf product or a highly customized solution, and should not be an afterthought.
The AVX antenna design team strongly recommends considering the antenna design and/or the antenna integration process as early as possible, ideally during the product design and the radio module selection. A perfect match between the radio and the antenna will ensure all wireless connectivity needs are met.
